One-screen vs. Multi-Step Hotel Reservations

Max Starkov and Jason Price of Hospitality eBusiness Strategies (HeBS) decide in favor of the multi-step form for booking engines. The article lists an extensive set of pros for the multi-step form and cons for the single step. Here are just a few:

User-Friendliness:

  • The multi-step booking process 'is easier on the eye' as it presents the information in 'installments', one step at the time.
  • The one-screen booking screen is exceptionally busy. The information is presented in one 'concentrated chunk', requiring extra time and focus on behalf of the user to figure out what is what, and where to begin and end.
  • Layout of the one-screen is confusing: Do you start top left and go to the right, and then move top to bottom (i.e. the Yahoo model)? Do you read the information column after column as it is in your local newspaper?
  • The fonts are too small and difficult to read (think senior citizen, baby boomers that all wear at least reading glasses, etc.).
  • The room descriptions are too 'skinny'-you have to scroll down to read more as opposed to having a page describing room descriptions and availability as it is currently on all major brands and intermediaries.
  • Rich Media: all of the images are so small and un-appealing.

Building and Managing a Successful User Experience Team

UIE's Christine Perfetti interviews two User Experience experts on Building and Managing a Successful User Experience Team.

On "selling" UX in an organization:

Another common pitfall is when a new UX team promotes yet another methodology on top of all the other methodologies within the organization – a development methodology, a change management system, a quality system, etc. Most organizations we know are weary of the ‘methodology du jour’ and want to get on with churning out what they need to churn out. Therefore, the best approach is to do UX ‘by stealth’. Figure out how to fit in what you need to do within the context of what already happens – that will make it seem much less imposing and more beneficial to all concerned.

On setting up a team:

The best place to start is by understanding your organization. It may seem obvious how a UX team can benefit your organization, but it’s very easy to fail. We recommend starting with an organizational analysis designed to help you understand the most effective way to set up the team.

On getting "buy-in" from  departments:

Stakeholders need to have an ongoing role in the project beyond simply providing input at key milestones. We recommend holding stakeholder workshops to collect their broad range of wants and needs. This allows you to identify the business drivers that can be balanced with those of users.

and from senior management:

Above all, we find it most effective to tie the results to real business objectives, even to what is most important to the senior managers. What is their next bonus tied to? What’s the one thing that’s going to jeopardize the executive’s BMW? It’s that thing that becomes the critical success factor for the project owner! The ‘beemer’ principle is absolutely relevant in our context, too. If you can tie the benefits of UX design to that (which you often can), you’ll certainly get their attention.

On disseminating usability findings:

Finally, it’s important to take time to emphasize the positives as well as the negatives. Unfortunately, often our job is to tell people that ‘their baby is ugly’. That can be very difficult to take. Therefore, although the suggestions often need to be strong (as opposed to "it would be good if you would consider possibly changing this to…"), you should definitely also provide feedback about things that work well about the design. The last thing you want is for your UX team to be simply seen as the voice of doom and gloom.

On staffing the UX  team:

UX team members need to value consistency (but not be a slave to it!), pay attention to detail (yet not dwell on it incessantly), and be pragmatic. Across the board, it’s important to find people who are good listeners and communicators, good facilitators, and excellent team players.

Faceted Metadata for IA & Search

The web site for the The Flamenco Search Interface Project offers presentations and tutorials on aspects of search and information finding that has informed the Flamenco search project at UC Berkeley. One resource, Faceted Metadata for Information Architecture and Search (pdf), is a CHI course presenting the findings on how the use of facets can improve searching and browsing large information collections.

Advantages of Facets

  • Can’t end up with empty results sets
    (except with keyword search)
  • Helps avoid feelings of being lost.
  • Easier to explore the collection.
    • Helps users infer what kinds of things are in the collection.
    • Evokes a feeling of "browsing the shelves"
  • Is preferred over standard search for collection browsing in usability studies.
    (Interface must be designed properly)
  • Seamless to add new facets and subcategories
  • Seamless to add new items.
  • Helps with "categorization wars"
    • Don’t have to agree exactly where to place something
  • Interaction can be implemented using a standard relational database.
  • May be easier for automatic categorization

The remainder of the presenation focuses on how eBay successfully uses facets for browsing and searching including interface lessons for improving usability. For example, they have found that placing facet controls for filtering and expanding results to be most successful when placed at the top of the screen versus the left side. Another lesson is to provide a truncated list of facet values - users have no trouble accessing the full list when needed.

In regards to "breadcrumbs" the traditional method (Facet > Sub-Facet > Value > Item) doesn't work well. Instead a more robust "panel" displaying facets chosen plus options for narrowing or expanding works much better when searching and browsing through vast amounts of items.
